.To all wwm it may concern.-

Be it known that I, CLARENCE S. TRAsK, a citizen of the United States, and a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spindle-Steps; and I do hereby declare that the following is a full, clear, and exact description of' the invention, which will ena-ble others skilled in the art to which it appertains to make and use the same,reference beinghad to the accompanying drawings, which form a part of this specifcation, and in whichd Figure l is a perspective View of my iinproved spindle-step, showing the same in position upon the frame-rail ready for operation,

only the lower end of the spindle and only aA portion of the frame-rail being shown. Fig. 2 is a vertical sectional view of the saine. Fig. 3 is a vertical sectional view ofthe same, showing the spindle-ease filled with oil, and illustrating the position assumed by the oil when the device is in operation. Fig. 4 is a perspective view of the ,flanged bearing or step for the lower end of the spindle detached from the case. Fig. 5 is a horizontal sectional view taken on the line a; x in Fig. 2; and Fig. G is a perspective view ofl the interior ease removed from the step-box, parts of the saine having been broken away for the purpose of illustrating the construction more clearly.

The same letters refer to the same parts in all the figures.

This invention relates to spindle-steps for spinning-frames; and it has i'or its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, andgeneral efficiency, which shall have capacity for receiving lubricating material in sufficient quantity for the device to run for a long period without refilling, and which shall be so constructed as to prevent the oil from escaping or from ascending the spindle, which would be obviously objectionable.

Vith these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A designates th'e rail of the spinning-frame, in which the step-box B is mounted by means of its downwardly-extending projection C, which enters a socket, D, in the rail, where it is retained by means of a screw, E, inserted from the side of the latter. The stcp-box B is pret'- erably of a cylindrical shape. The projection C is provided with a recess extending nearly to its bottoni, in which is placed the block F, which is also recessed nearly to its bottom, forming a step or bearing, II, for the lower end ofthe spindle. This block F is provided with vertical flanges G, which lit in the recess in the'projection C tight enough to keep it from turning with the spindle. These flanges also form channels for the oil to pass down from the upper part of' the step-box.

Between each ofthe flanges G,directly above the bottom ofthe bearing, is a horizontal pel'- foratiou, l, through which the oil passes from the spaces between the flanges to the step H.

The spindle case J is a shell fitting within the step-DOK B, and provided at the top with a concave or cup-shaped cover, L, having a flange, K, and a central perforation, through which the spindle passes, and which forms a bearing for the same. This cover isalso provided with two perf'oratious, N N, through which the oil is introduced within the case J.

In operation the case J and the spindle are placed in position, and the spindle-case is then filled with oil about to the level of the lower edge of the cup or flange L The oil will fill the spaces between the flanges G, and pass through the perforations I to the bearing at the lower end of the spindle, which is thusI kept freely supplied with oil.

In operation the oil contained in the case will, by the centrifugal action ot' the spindle, be thrown or forced in an outward direction against the walls of the case, by contact with which it is driven in an upward direction against the cup or flange L, as shown iu Fig. 3 of the drawings.

The general construction is simple, and the oil-holding capacity is so great that the device may run for a very considerable period without attention.

Having thus described lny invention, I claim and desire to secure by Letters Patent of' the United States* As an improvement in spindle-steps, the combination of a step-box having a down- ESO IOO

wardly extending` projection, a cylindricall bearing-block arranged in a socketin said projection, andV having exterior vertical flanges tting tightly in the latter; and horizontal perforatons arranged between the flanges and directly above the bottom of the step or bearing7 and an inner ease ltted in the step-box, and provided at its upper edge with a downwardly and inwardly extending annular con- 10 cave flange or cup provided with openings or perforations, all arranged and'operating substantially as and for the purpose herein set forth.

In testimony that I claim the foregoingas my own I have hereunto aiixed my signature in presence of two witnesses.

CLARENCE S. TRASE.
